Holostylis reniformis biosynthesizes 8-8' linked lignans without 9,9'-oxygenation. To elucidate the biosynthetic pathways to these lignans, the reputed precursors [U-(14)C]phenylalanine, [9-(3)H(1)]coniferyl alcohol, and ...

Aryltetralol and aryltetralone lignans were isolated from the hexane extracts of the roots of Holostylis reniformis. Their structures were determined by spectroscopic methods and chemical transformations. (c) 2006 Elsevier ...

Root extracts of Holostylis reniformis (Aristolochiaceae) yielded three new natural sesquiterpenes, a sesquiterpene with an unusual carbon skeleton, 4,5-seco-guaiane (7-epi-11-hydroxychabrolidione A, 1), a nine-membered ...

Aryltetralol and aryltetralone lignans were isolated from the hexane extracts of the roots of Holostylis reniformis. Their structures were determined by spectroscopic methods and chemical transformations. (c) 2006 Elsevier ...

Abstract Two new lignans, an aryltetralol and its methyl ether analogous, were isolated from Holostylis reniformis (Aristolochiaceae) together with futokadsurin C and (-)-8′-epi-aristoligone. The latter was also obtained ...

Aryltetralone lignans and two 7,8-seco-lignans were isolated from the acetone and hexane extracts of the roots of Holostylis reniformis, together with (-)-galbacin. Their structures were determined by spectroscopic methods. ...
